Sendmail - accepting mail for new domain
I have sendmail running on RHEL 5 and I currently accept mail for one domain foo.com and one subdomain sub.foo.com. As the result of a branding exercise I need to also accept mail for newfoo.com.
My goal is to have messages sent to the new addresses delivered to the existing mailboxes. Can I do this simply by adding newfoo.com to /etc/mail/local-host-names or is something required in /etc/mail/virtualusertable as well?
Thanks in advance.
